I have 60 onion coins in my wallet and the only airdrop I received was 0.008 onions twice...is this even worth it ?
That 0.008 was for your activity (posts you made) on the Deep Onion forum. You need to have at least 100 Onions in your wallet for the airdrop.
The main airdrop gives you 20-28% returns on your investment. You can decide for yourself if it is worth or not.
Here are the rules for the airdrop:
